to the camera back behiinl i o' rw the giouiid glass l ie attachment l is composed of a body haring an open front, and around this open t f. .tf1-,1 i fn l C .l t, l., 1 non is .as cnei.. a rame oi icc anguai ni ils l for securing the attachment lo the traine r/ 'wie body of the :ltl'aclinien, is foi'lncd of a back il and sides li. (lee bacl-r and sides consisting of a piece lcatlun' or equivalent lfexible material, and the sides are triangni; r in shape and have :i vcnlral crease T w ereby the sides fold inwardly, bellows-like. On the inner surface of the back I3 is reflecting mirror l which is reinforced or backed by a piece of cardboard El glu-wl to the mirror and to the back 5 of the attachment. The bottom edge of the back 5 ad the front edges of the sides 6 are secured te the frame 1 by rivets which pass through an inside metal frame i1 corresponding to the frame 1. The sides are so proportioned that when the device is open, as shown in Fig. 1, the mirror will be inclined at an angle of thirty degrees more or less to the ground glass a of the camera, so that the image focused on the ground glass can be seen on the mirror by iooling downwardly into the attachnient. T ie top of the attachment when open is clised by a cover 1.2 also of leather or equivalent flexible material, and the front edge of this cover is riveted between the frames 1 and 11, The cover has back and side flaps 13 and l-l which extend downwardly over the outside of the back 5 and sides 6 of the body of the attachment, and in t-he cover 12 is a view opening 15 whereby the user can lool: into the attachment to see the image. A central socket 1G is provided on the flap 13 to engage a central stud 1G on the back 5 adjacent the top of the latter, so that when. the attachment is open, the cover 12 is held down in the position shown in Fig. 1. -lhen the device is closed, the sides G of the body are folded inwardly and the top or cover 12 with the flaps 11i folded thereunder folds down over the back "3 of the body and it is locked in this position by means of sockets 17 on the plate 13, which engage studs 1S on the back 5 adjacent the bottom thereof, and when the attachment is thus folded it lies flat against the back of the camera and takes erin and of such size as to border the open-- np very ,little lopinie. lVhen. iliolded oi? open the attachment presents a very neat appearanee and eontlfibnes inatei'iall)T lo the pleasni'e of photogi'aphing7 as the image can he easily and quickly Yfocused Without the need ol2 a, cloth lfioin the foregoing description taken in Connection with the aeeonipanying dran*- ingg" the advantagea of lhe eonsliinecion. and method o? operation will he readilyT nndeisood hi' those Skilled in the aixt to which the ini'ention appei'tains, and while l have desci'ihed the principle oil? ope ation, lo ge hei n'il'h the device which l non' co1 Qidei,l t'o he l'he heat einhodin'ienl thereof, l desire o have il nn flerstood il at the dei'ieo shown is merely' illnn'u'alii'e and that anch ohaing'ea ina)v he inade when desired as 'fall Within the scope of the appended elailns.
